Speccaton of Letters Patent.

Patented March 3, 1908.

Application filed October 23, 1907. Serial No. 398,767.

To all whom it may concern:

Be it known that I, WILLIAM P. ELEM- ING, citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Closures, of which the following is a specification.

My invention pertains to closures for hot water bags and the like, and it has for its object to provide a simple, compact and strong closure through the medium of which Qa hot water bag or like device may be hermetically sealed, and one that is adapted to be expeditiously and easily opened and closed and yet is not liable to casually open during the use of the bag.

With the foregoing in mind, the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this speciication, in which:

Figure 1 is a view showing novel closure'in elevation as properly positioned in a water bag, the latter being shown in vertical section. Fig. 2 is an elevation of the plug of the closure removed from the casing thereof. Fig. 3 is a vertical, diametrical section of the closure casing. Fig.- 4 is a plan view of said casing. Fig. 5 is an inverted plan view of the casing.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is so much of a water bag as is necessary to show the application of my novel closure; the said bag being made of rubber and constructed in the conventional or any other manner compatible with the practice of my invention.

B is the casing of my novel closure which is secured by cement B as shown, or by any other suitable means in the mouth of the bag A. The said casing B is preferably made of metal in cylindrical form, and is provided with the following features, to wit: a vertical-central bore a, diametrically opposite, vertical grooves o communicating with and extending laterally outward from said bore, oppositely disposed, curvilinear cams o formed on the lower end of the casing and extending in opposite directions from the lower ends of the grooves b, and an interiorly bearing for the elastic gasket hereinafter set forth.

C is the plug of the closure which is also preferably of metal, and D is the elastic gasket, preferably of rubber, arranged on and carried by the plug. The said plug C is of a diameter to snugly occupy the bore a of the casing B, and is provided at its lower end with diametrically-opposite, radial lugs e which are preferably beveled at their upper sides and are arranged to be moved down and up in the casing grooves o and to be moved in a circular direction against the undersides of the cams o. The plug is also provided with a shoulder f of the proportional diameter illustrated, and a finger piece g extending above said shoulder. The gasket D is annular in form and surrounds the plug below the shoulder f and is preferably, though not necessarily, connected to the shoulder through the medium of suitable adhesive.

It will be clear from the foregoing that when the plug C is moved downward in the casing B to carry the lugs e below the lower end of the casing, and is then turned on its axis in the proper direction to move the said beveled upper end d, the latter to aord a A lugs e against the cams c the gasket D will be compressed against the upper end of the casing and a water-tight closure of the water bag will be effected. It will also be understood that the compressed elastic gasket holds the lugs e under pressure against the cams c, and hence casual movement of the lugs is precluded and there is no liability of the plug being accidentally released. When, however, it is desired to open the closure, it is simply necessary for the user to turn the plug through a part of a revolution in the direction opposite to that first stated, and then draw the plug endwise out of the casing B.

By virtue of the casing B having the interiorly beveled upper edge, it will be apparent that when the plug is drawn downward in the casing by the means described, the gasket D will be crowded in the upper end of the casing and in that way the closure will be rendered perfectly water tight.

The construction herein shown and described constitutes the preferred embodiment of my invention, but it is obvious that in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of my invention as define d in the claim appended- Having described my invention, what I claim and desire to secure by Letters-Patent, 1s:

The herein described closure consisting essentially of a portion to receive a plug, the said plug, and a gasket 5 the said portion having a vertical-central bore and diametrically opposite vertical grooves communicating with the bore and extending laterally therefrom and also having oppositely disposed cams on its lower end extending in opposite directions from the lower ends of said grooves, and an interior bevel d at its upper end, and the plug being of a diameter to snugly occupy gg r881,06*?

said portion and having diametrically-oppo'- site, radial lugs at its lower end and a shoulder at its upper end and also having a fingerpiece above the shoulder, and the gasket being arranged on the plug below the shoulder thereof and also arranged on downward movement of the plug in said portion to be crowded in the upper beveled end of the portion.

VIn testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
